问C#调用EXCEL之后进程退出的问题！！！多谢!!

Question

Process[] ps = Process.GetProcessesByName("Excel.exe");
if(ps.Length>0)
 ps[0].Kill();

Answer 1

Process[] ps = Process.GetProcessesByName("Excel.exe");
if(ps.Length>0)
 ps[0].Kill();說的是在已經用process起動了的excel.exe啊,如何找到進程中的excel.exe啊,才是問題的關鍵所在

Answer 2

Dim myProcesses() As Process
   Dim instance As Process
   myProcesses = Process.GetProcessesByName("Notepad")
   For Each instance In myProcesses
      instance.Kill()
   Next

Answer 3

public void DestoryExcel()
{
oBook.Close( false, null, null );
oExcel.Workbooks.Close();
oExcel.Quit();
System.Runtime.InteropServices.Marshal.ReleaseComObject( oRange );
System.Runtime.InteropServices.Marshal.ReleaseComObject( oWorkSheet );
System.Runtime.InteropServices.Marshal.ReleaseComObject( oSheet );
System.Runtime.InteropServices.Marshal.ReleaseComObject( oBook );
System.Runtime.InteropServices.Marshal.ReleaseComObject( oExcel );
oRange = null;
oWorkSheet = null;
oSheet = null;
oBook = null;
oMissing = null;
oExcel = null;
GC.Collect();
}
